Deuteronomy 9:18 Meaning and Commentary

Deuteronomy 9:18

And I fell down before the Lord
In prayer for Israel who had sinned; but this he did not immediately after he had broken the tables, but when he had first ground the calf to powder, strewed it on the water, and made the children of Israel drink it; and when he had chided Aaron, and ordered the sons of Levi to slay every man his brother:

as at the first forty days and forty mights;
which is to be connected, I think, not with what goes before; for we read not that he fell down before the Lord, at the first time he was with him so long in the mount; but with what follows: "I did neither eat bread nor drink water"; as he neither ate nor drank the first forty days, so neither did he these second forty; see ( Deuteronomy 9:9 )

because of all your sins which ye sinned, in doing wickedly in the
sight of the Lord, to provoke him to anger;
for they were guilty of more sins than one; besides idolatry, they were guilty of unbelief, ingratitude which were notorious and flagrant, were done openly and publicly, in sight of his glory and majesty on the mount; all which must be very provoking to him, and on account of these Moses prayed and fasted.

Deuteronomy 9:18 In-Context

16 There below me I could see that you had sinned against the LORD your God. You had melted gold and made a calf idol for yourselves. How quickly you had turned away from the path the LORD had commanded you to follow!

17 So I took the stone tablets and threw them to the ground, smashing them before your eyes.

18 “Then, as before, I threw myself down before the LORD for forty days and nights. I ate no bread and drank no water because of the great sin you had committed by doing what the LORD hated, provoking him to anger.

19 I feared that the furious anger of the LORD, which turned him against you, would drive him to destroy you. But again he listened to me.

20 The LORD was so angry with Aaron that he wanted to destroy him, too. But I prayed for Aaron, and the LORD spared him.
